I have no clue. I have never sprayed a car. You're the expert - you should be telling us!

Sounds expensive though.

Edit - Brian -- You know I am serious about that. I am tired of being told by companies trying to sell their products what is true or false. It is up to people who know what they are talking about (like yourself) to debunk these myths and stop people wasting their hard earned cash on crap. Thank god for forums and the internet, if you look hard enough you will always find the truth. (Also thank you Jon for all your hard work on your powerTV detective work)
